Hello I have big ambiguity in using this word: UNTIL. Does it include the thing after word UNTIL or it means that thing is not included?
Here are two examples:
The TV Show was good until 3rd serie. - Does it mean 3rd serie was the last good serie or the last good serie was 2nd and 3rd was already bad?
There were no problems until the 5th car/customer. - Does it mean 5th car/customer was already problematic? Or that 5th car/customer was OKAY but after 5th there were problems?
I hope you can see my problem, in this. If I should not use word UNTIL what should I use to be more clear? Can somebody give me proper answer? Thank you.
